Hum! Do you mean ( I haven't caught up all the way on this thread ) that 
the two switches are inter-connected?

	SWITCH0 <-> SWITCH1,
	ETH0 <-> SWITCH0, and
	ETH1 <-> SWITCH1.

I am working at, as time permits, getting three Ethernet devices working 
on one host and the guests needing to access two of the networks.  WAN1, 
WAN2, LAN with each guest needing either WAN1 or WAN2 and LAN access. 
In reality WAN1 and WAN2 both use the same feed (router etc. ) into the 
internet but they use very different address ranges.

Is this similar to you are trying to do?
